This invention relates to mixing mills for properly and thoroughly mixing dry powders or dusts to produce a spraying and dusting compound to combat fungus and insect 5 pests of economic plants, for mixing poultry and stock feeds, fertilizers, and other dry mixtures.

Referring to the accompanying drawings forming a part of this specification in which lo like reference characters designate like parts in all the views.

Fig. 1 is a side elevation of the machine, the drum, sifter box and rotatable drumholder being shown partly in section;

Fig. 2 is a section on the line 2 2 of Fig. 1;

Fig. 3 is a vertical section through the sifter box, taken on the line of the shaft and partly broken away;

Fig. 4 is a section on the line M of Fig. 3;

Fig. 5 is a perspective View of the collapsible dasher; and,

Fig. 6 is a similar view of a container for chemicals to be placed in the hopper.

, Referring' to the drawings, 1 indicates the D base or support of the mixing mill comprising side bars, the ends 2 of which extend upwardly from the base and thence horizontally, as shown. Hinged to the supports 2 u at 3 is a platform 4 to the end of which w are secured upright retaining arms 5 hav-- ing a locking means 6 on the end of the same adapted to engage the ends of the lateral members of the supporting arms 2.

The platform 4 is adapted to accommodate a drum or mixing chamber 7, within which is placed a removable collapsible dasher 8.

Supported by the horizontal end portions of the arms 2 is a sifter box 9 at the bottom of which is a semi-cylindrical sieve 10. Pass- U ing horizontally through the sifter box 9 is a small shaft 11 to which are secured brushes 12 by means of steel plates 12a bolted to the same and the brush blocks 12b, the bolt holes i in the steel plates being slotted to permit of adjustment of the brushes. Fixed on the exposed end of the shaft 11 is a sprocket or 0fear 13. Mounted on the top of the sifter box 9, which may be either separate or made i a part of same is a hopper 14 adapted to receive a plurality of small containers l5 which maybe lsquare `or circular in form. Hinged inthe bottom of thehopper Y134 is a movab -e partition A ada ted to be placed at different angleswithin the hopper. i v

A rotatable drum carrier ismoun'ted upony the base 1, this carrier comprising opposed' spiders 19j, to which are secured vshort shafts 18, 18a, -whichare .journaled ,in bearings 17 upon pillars 16V which project 'upwardly from th'ebase.v The 'arms of the spiders are connected by fiat ,bars ,'20, ,one1 of which, 20th', is readily detachable, Jt'liifs bar being 'connected to 'tbe 'Spiders by 'wing butanol, so that the ,dfuim be readily/placed withinf'be carrier'in horizontal psiubn. d" p On the Outer end fshaft I18 i's-a 'sprocket or gear 21, andoperative chain 22 Aengages the gears 13 and 21. the outer eind of shaft 18L is'a loose' pulley 23 and: a Efixed' a pulley2 4. Y Y c C i The operation "f themill is as follows: A receiving drui'i"'orfmixiiigrhainiler lWitlifa flasher init is p'lacefdon thefplatfrm, with its 'open end beneath rbb sifter box 9. The smaller quantitifesiof the :chemicals and'other "u ingredients A"areweighed outl and put i'nj'the sfilallv 'containers which' in tun l'are placed in' theI l'z'trge hopper The jlargrquantiti-es `f clleiniibalsg'dust 'andlothei ingredients fare placed'iii the la-'rgb yho'pflie'r '-aroifmd' the -sfmfall containers which, are then withdrawn", 'the hinged `b''o-tftins'f beingf'r opened bffo'r such removal, the contents are depositedin; columns surrdundec"by the bulk material or materials. The different quantities may also be gauged by the movable partition within the hopper which is placed at any angle desired. Power is applied through the medium of the fixed pulley 24, shafts 131 and 18, gears j 21, 13 and chain 22, which causes the brushes J 12 in the sifter box to revolve drawing the contents from the hopper 14 forcing said ingredients through the sieve 10, blending, breaking the lumps and sifting the material ,f. together into the receiving drum or chamber. When the hopper is empty the drum or mixing chamber 7 is removed, a tight friction lid pressed into the open end, the drum 7 placed in the horizontal drum carrier above described, and the mixing and blending continued, the dasher holding back a portion of the material, and allowing other portions to fall by, through which operation the contents are thoroughly mixed. While the latter operation is being performed, the contents of the hopper 14 are drawn from the same by the revolving brushes 12, the materials mixed and forced through the sieve 10 into another drum or mixing chamber 7. 'Ihus it will be seen that two operations are being performed at the same time.

The drum or mixing chamber in the rotatable drum-carrier is removed, the dasher taken out, an airtight head put in, and the drum with its perfectly mixed and blended Y' contents is ready for shipment or storage. Throughout the entire operation the ingredients are confined to the drums thus giving a dust leali proof operation. Y

What I claim and desire to secure by Letters Patent is:

1. In a machine for filling and mixing the contents of cylindrical drums, a base, supporting arms projecting upwardly from the base and having horizontally extending ends, filling devices mounted' on said ends, a platform hinged to the base and adapted to support the drum in upright position beneath the filling devices, and means on the free end of the platform for latching it to the ends .of the supporting arms.

2. In a machine for filling and mixing the contents of cylindrical drums, a base, supporting arms projecting upwardly fromrthe base and having horizontally extending ends, lling devices, including a rotatable brush, mounted on said ends, means for supporting a drum in upright position beneath said devices, a drum-carrier supported on the base and adapted to hold the drum'in horizontal position,v said carrier comprising opposed spiders rotatable about a horizontal axis and bars connecting the arms of said spiders, one of said bars being detachable, and gearing connecting said carrier ywith said rotatable brush.

In testimony whereof I hereunto affix my signature. y
